Not sure where to travel in Europe in September? This time of year hits a sweet spot. The weather is still warm in most places, but the summer crowds have cleared out, making it the perfect time for many travelers. During the shoulder season, flights are easier to book, prices start to drop, and everything feels a little more relaxed. September is a good time to visit popular spots that are usually packed in July or August, especially if you want fewer crowds and better weather.
This guide includes 9 of the best places across Europe that are actually worth visiting in September. Whether you’re looking for somewhere by the water or want to spend your time walking through older neighborhoods without overheating, here’s where to go.
1. Greece
If you’re deciding where to travel in Europe in September, Greece is one of the few places where it still feels like summer. The sea stays warm, ferries keep running on full schedules, and prices start to drop significantly, especially if you avoid the big-name Greek islands.

Where to go
Start in Athens if you want to see the major ancient ruins without the summer crowds. The Acropolis, Ancient Agora, and other historic sites around the city center are still busy, but early September gives you better weather and fewer people. Go early in the day to avoid heat and tour groups.
If you’re planning to visit the islands, September gives you options:
- Paros and Naxos both have sandy beaches, walkable towns, and strong ferry connections. The crowds thin out just enough after the first week.
- Milos is quieter and better for a slower pace. Great for a boat trip if you want to swim and explore sea caves.
- Santorini is still packed but easier to navigate in late September, and sunsets in Oia are slightly less chaotic.
- Crete stays hot the longest. It’s one of the best places in Europe for warm weather this late in the season. Spend time in Chania or Rethymno for a mix of beaches, historic towns, and food that doesn’t feel watered down for tourists.
You can also build in a few day trips if you’re based in Athens. Delphi is great for archeological sites, and Hydra works if you want a quick island escape without flying or dealing with long ferry rides. First time traveling to Greece?
